While working through one of my art books yesterday morning I stumbled upon the word: “Calligram.” Turns out a Calligram “is a poem, phrase, or word in which the typeface, calligraphy or handwriting is arranged in a way that creates a visual image” (Definition courtesy of Wikipedia).

Here's a classic example of the Calligram form from Calligrammes by the French author Guillaume Apollinaire. Similar to "Concrete Poetry", Calligrams utilize more typographic elements in their presentation than visual structure to present their meaning to the reader.
